Tasks 1.1-1.6 cover the bulk of Front A: the gemini_cli adapter module
plus all importer edits (ai_client, app_controller, gui_2,
project_manager, api_hooks) and the 7 dedicated gemini_cli test files.
Remaining Front A tasks (1.7-1.11) cover the mock provider, the 11 sim
test rewrites, the minor test edits, the doc updates, and the batch
checkpoint.
